HENRY cQr'nA-Rson,
OF NEW YORK, N.y Y.
Letters Patent No. 113,557, dated April y1.1, 1.871.
IIVIFROVEMEN-'l IN METALSYCREWS AND NUTS.
The Schedule referred to in these Letters Patent and. making pax-t of the same.
To all whom it may conce/rn:
Be it known that I, HENRY G. PEARsoN, of the city, county, and State of New York, have invented certain Improvements in Metal-Screws, vand Nuts for the same and I do hereby declare that'theV following, taken in connection with the drawing which accompanies and forms part of this s pecitication,jis a description of my invention sucient to' enable those skilled in the art to practice it.-
My invention consists in a novel formation of the thread of a screw or bolt to enable it the better to hold its position when subjected to jars and jolts, without turning in the nut or other objectin Vwhich it is-inserted; in a corresponding formation of the .threads vof anni'. applicableI to be used with such a screw or bolt; and in combining with such a nut aconvex steel washer, as hereinafter set forth. I make my screw with a series of indentations or grooves, either on one or both sides of its thread, at
It will be seen that this construction admits of readily screwing the screw to place, lbut oiiers a iirxu and positive resistance againstits getting accidentally lloosened by being turned backward.
,Figurel illustratesra uut constructed as a countervpart of the screw or bolt, having its thread notched on one face or sidecorrespondingly with tig. 3
O nlyone form of` `notch is shown, but the thread may'have itsl series ofnotches or indeutations of any appropriate configuration 'adapted to that of the holt 0l'. screw., Y
Figure 5 is a central section, and Figure 6, a plan oi'a concave metal washer, preferably ot' steel, designed to be used iu some cases in connection with my improved unt, and placed between the nut and the object held hy the screw and uut.
` VIts object is to secure a still tighter hold by tending, when compressed, to force the swells or elevations ofthe thread ot' the screw into the correspouding,r depressions or cavities on the thread of the uut, and (vice versa.
Y Instead of such a washer an India-rubber or other elastic washermay beV used.
Figure 7 lshows in section,.and Figure 8 in plan, one of my improved notch-threaded nuts, with one of these metallic concave washers loosely affixed thereto. I connect them as follows:
On that side of the nut which is to bear against the object held or fastened, a shallowv depression, a little deeper than the thickness of the washer, is made, circular, square, or otherwise, asthe case may be, to con form to the form of lthe washer, and slightly grooved to receive its edge. The washer is then inserted therein, its convex face projecting beyond the face of lthe nut, as seen in the gure; and to secure it to place a few blows or indentations at theedge of the depression will expand the metal at such points suiciently to overlap the washer andV keep it in its place; orl
punch-holes may be` struck aroundin several places. It must lie loosely enough in its seat to permit its edge, when 'the washer is temporarily dattened by screwing the nut vagainst a surface, to spread at its edges, and also when released to resume its normal position.
In some cases I slit or cut the washers from either their inner or outer edge nearly through to the other edge, iuorder to render them more elastic. One of these convex washers may, if desired, be lodged in,-
each face of the nut.
My invention is applicable in 4almost every branch of the artsrwhere bolts and nuts or male and vfemalescrews are used. It will be found especially valuable in all cases where there is much motion and jarring of the machinery, and a consequent tendency vto a loosening of the parts; as, for instance, in axle nuts, to prevent the wheels of vehicles from running oii; in water-faucets', the screws of which should be held permanently to prevent leakage; in connecting the valveplate to the valve-stem in a steam-engine; in securing ish-plates toconnect the ends of railway-rails, 860.]
I claim- 1. 'A bolt or screw having a series of indentations on one or both sides ofthe thread, substantially as de scribed, in such manner that the indentations will act as a series of detents, for the purpose set forth.
2. A nut havinga series ofindentations on its thread, substantially as described, and adapted'for use in connection with a bolt or screw indented Vas described.
3. Such aunt, when usedinconnection with a loose convex steel-washer, or itseqnivalent, as described.
